Given that all distros for sure did run 'autogen.sh' in a large number
of packages since years it is easy to guess that in general it just works.

And if Xen decides that a certain autoconf version is is the minimum,
configure.ac has a knob for that the minimal required tools version.
As I said, autoools are not runtime dependencies, nor is make|flex|bison.

So, please consider moving these generated files to .gitignore.
